已有大量研究揭示了近似数量系统与计算流畅性的相关关系, 但缺少对二者关系原因的系统检验与论证。视觉形状知觉假设有别于传统的数量领域特异性解释, 认为对形状的快速知觉是近似数量系统与计算流畅性的共同认知机制, 即视觉形状的快速知觉能力可以解释二者之间的相关关系。近似数量系统和计算流畅性在加工过程中依赖对形状的快速知觉, 二者在加工过程中都涉及了复杂视觉刺激的快速处理。视觉形状知觉假设得到了一系列研究结果的支持, 但局限在视觉形状知觉与二者关系的探讨上, 视觉形状知觉在二者关系中作用的加工机制仍不清楚。未来研究需要结合多种研究方法和技术, 多角度深入探讨视觉形状知觉在二者关系中作用的认知与脑机制, 并将研究结果应用于数学课堂教学和计算困难的干预中。 相似文献

Against the background of a reconstruction of the reasons for the vanishing role of remembering in the history of psychoanalysis, Botella's (2014, Int J Psychoanal, 95 ) arguments regarding the therapeutic significance of reconstruction and remembering and of the therapist's role are discussed. The difference between intellectual reconstruction and actual emotional remembering are underlined, the term regredience is compared to competing concepts such as equally suspended attention, countertransference and reverie. It is argued that to conceptualize the use of countertransferential associations for reconstructing past traumatic events is difficult with a monadic conception of the unconscious and problematic both in terms of truth claims and in terms of achieving a shared creative atmosphere in which therapist and patient participate alike. It is concluded that historical truth may be important for traumatic experiences, and that biographical reconstruction and change in the subjective life story help to make sense of neurotic patterns and integrate diachronic identity. 相似文献

A 2‐year longitudinal study of 33 children aged 4–6 years was conducted to clarify the developmental relationship between calculation skill and finger dexterity, as well as the selectivity of the predictive power of finger dexterity on later calculation skill. We examined individual developmental change in the relationship between addition performance and finger dexterity and observed whether children fit a linear developmental pattern. Multiple regression analysis showed that participants' performance on addition tests was strongly predicted by their finger dexterity. However, their performance on vocabulary tests was not strongly influenced by finger dexterity. These findings suggest that calculation skill in children aged 4–6 years is strongly related to finger dexterity. 相似文献

Mild traumatic brain injury (mTBI) is a leading cause of injury among children, with approximately 15% of children experiencing a TBI prior to 15 years of age. Acutely, mTBI has been associated with a range of cognitive, physical, emotional and behavioural impairments. However, few studies have examined outcomes beyond five years post injury, long before the developmental process is complete and the full extent of any deficits may manifest. Our group had the unique opportunity to use data from a longitudinal birth cohort of 1265 children (Christchurch Health and Development Study) to examine the long term outcomes of early injury (0–5 years). Information about these children, including mTBI events, had been collected at birth, 4 months and at yearly intervals until age 16, and again at ages 18, 21 and 25 years. We found that even after statistical control for a wide range of child and family confounds, children who had been hospitalized for an mTBI had increased inattention/hyperactivity and conduct as rated by mothers and teachers over ages 7–13 years. Increased rates of psychiatric disorders were over 14–16 years for those injured in the preschool, including symptoms consistent with Attention Deficit/Hyperactivity Disorder (ADHD), Odds Ratio = 4.6, Conduct Disorder (CD), Odds Ratio = 5.6 and Substance Abuse (Odds Ratio = 9.1). Over ages 21–25 ongoing behaviour problems were assessed using self‐reported arrests, violent offenses and property offenses. Compared to non‐injured individuals, mTBI groups were more likely to be arrested, involved in property, and violent offences. We controlled for a wide range of factors and there was still clear evidence of ongoing problems for individuals who had experienced a mTBI compared to their non injured counterparts. These findings provide compelling evidence of long term psychosocial and psychiatric outcomes following mTBI. 相似文献

Explicit social pressure has been shown to be a powerful motivator of prosocial behavior‐like voting in elections. In this study, I report the findings of a randomized field experiment designed to study the impact of more subtle, implicit social‐pressure treatments. The results of the experiment, conducted in the October 2011 municipal elections in Key West, Florida, demonstrate that even subtle, implicit observability cues can effectively mobilize citizens to vote, perhaps as much as explicit surveillance cues. The findings speak more broadly to our understanding of human decision making, and even evolution, and provide fodder for the claim that humans are evolutionarily programmed to respond to certain stimuli. I interpret the evidence to support the notion that evolutionarily charged impulses, like exposure to images that implicitly signal the potential for surveillance and observability, are sufficient to overcome powerful collective action incentives to free ride. 相似文献

Although studies have examined the effects of interventions focused on preterm infants, few studies have examined the effects on maternal distress (anxiety, depressive symptoms, post-traumatic stress symptoms, parenting stress) or parenting. This study examined the effects of the auditory–tactile–visual–vestibular (ATVV) intervention and kangaroo care (KC) on maternal distress and the mother–infant relationship compared to an attention control group.240 mothers from four hospitals were randomly assigned to the three groups. Maternal characteristics in the three groups were similar: 64.1% of ATVV mothers, 64.2% of KC mothers, and 76.5% of control mothers were African American; maternal age averaged 26.3 years for ATVV mothers, 28.1 for KC mothers, and 26.6 for control mothers; and years of education averaged 13.6 for ATVV and KC mothers, and 13.1 for control mothers. Mothers only differed on parity: 68.4% of ATVV and 54.7% of KC mothers were first-time mothers as compared to 43.6% of control mothers. Their infants had a similar mean gestational ages (27.0 weeks for ATVV, 27.2 for KC, and 27.4 for control) and mean birthweights (993 g for ATVV, 1022 for KC, and 1023 for control).Mothers completed questionnaires during hospitalization, and at 2, 6 and 12 months corrected age on demographic characteristics, depressive symptoms, state anxiety, post-traumatic stress symptoms, parenting stress, worry about child health, and child vulnerability (only at 12 months). At 2 and 6 months, 45-min videotapes of mother–infant interactions were made, and the HOME Inventory was scored. Behaviors coded from the videotapes and a HOME subscale were combined into five interactive dimensions: maternal positive involvement and developmental stimulation and child social behaviors, developmental maturity, and irritability.Intervention effects were examined using general linear mixed models controlling for parity and recruitment site. The groups did not differ on any maternal distress variable. Kangaroo care mothers showed a more rapid decline in worry than the other mothers. The only interactive dimensions that differed between the groups were child social behaviors and developmental maturity, which were both higher for kangaroo care infants. Change over time in several individual infant behaviors was affected by the interventions. When mothers reported on the interventions they performed, regardless of group assignment, massage (any form including ATVV) was associated with a more rapid decline in depressive symptoms and higher HOME scores. Performing either intervention was associated with lower parenting stress. These findings suggest that as short-term interventions, KC and ATVV have important effects on mothers and their preterm infants, especially in the first half of the first year. 相似文献

The search for different options before making a consequential choice is a central aspect of many important decisions, such as mate selection or purchasing a house. Despite its importance, surprisingly little is known about how search and choice are affected by the observed and objective properties of the decision problem. Here, we analyze the effects of two key properties in a binary choice task: the options' observed and objective values, and the variability of payoffs. First, in a large public data set of a binary choice task, we investigate how the observed value and variability relate to decision‐makers' efforts and preferences during search. Furthermore, we test how these properties influence the chance of correctly identifying the objectively maximizing option, and how they affect choice. Second, we designed a novel experiment to systematically analyze the role of the objective difference between the options. We find that a larger objective difference between options increases the chance for correctly identifying the maximizing option, but it does not affect behavior during search and choice.
